Squiz.WhiteSpace.FunctionSpacing.SpaceAfterLast should not apply if there is comment after the function.

With a config of one line between functions and 0 after the last one, I still expect to not have error with the following code:

interface Foo 
{
    /**
     * @return bool
     */
    public function bar();

    /**
     * Comment
     */
    // Comment
}

There is the same issue with

interface Foo 
{
    /**
     * Comment
     */
    // Comment

    /**
     * @return bool
     */
    public function bar();
}
